Rainproof performance of tarpaulin fabrics

Tarpaulins generally have rainproof performance. In people's eyes, how many mm of water column per square centimeter is used to calculate its rainproof performance. For example, high-quality tents will reach 3000-4000mm, so that their rainproof level will rise to resist continuous rainstorms. General tents are rainproof above 1500mm water column, which can only prevent moderate to heavy rain. Although the rainproof index of the tent is relatively high, its ventilation is also an important issue. Because if it is not breathable, it will also affect the quality of the products in our tent. Only when both goals are achieved can the high quality of the products be guaranteed.
